Hereinafter, the electronic device according to various embodiments
of the present disclosure will be described in more detail.
The electronic device according to various embodiments of the
present disclosure may be applied to a WLAN system. The WLAN system
includes one or more basic service set (BSS). The BSS is a set of
stations (hereinafter, STA) that may be successfully synchronized
to communicate with each other. The BSS may be classified into an
independent BSS (hereinafter, IBSS) and an infrastructure BSS. In
the IBBS, direct communication between the STAs may be made and an
operation type between the STAs may be defined as an ad hoc
network.
To connect the STA to the BSS, a procedure of synchronizing with a
base station needs to be performed. Further, to access all services
of the infrastructure BSS, the STA needs to be associated with the
base station. The association procedure is dynamically performed
may include the use of a distribution system service (DSS). An
inter-STA supportable direct distance may be physically limited.
The distance may be sufficient in some networks, but if the
difference is insufficient, coverage extension may be required.
Accordingly, the BSS may be configured as one element in the
extended form of the network including the plurality of BSSs. As
such, an architecture element used to interconnect the BSSs may be
called a distribution system (DS).
The DS is mechanism for connecting a plurality of access points
(hereinafter, APs) and is not necessarily a network. Therefore, as
long as the DS may provide a predetermined distribution service, a
type of the DS is never limited. For example, the DS may also be a
wireless network like a mesh network and may also be a physical
structure for interconnecting the APs.
In the WLAN system, a distribution system medium (DSM) and a
wireless medium (WM) may be logically classified. Each logical
medium may be used for different purposes by different elements of
the architecture. The DS provides a logical service to manage
seamless integration of the plurality of BSSs and address mapping
to a destination, thereby supporting mobility of a device.
The AP may be a support apparatus so that the associated STA may
access the distribution system through the WM Data may be
transmitted between the BSS and the DS through the AP. Here, all
the APs may be the STA, and therefore the AP also has entity having
an address. However, for communication through the WM and
communication through the DSM, the addresses used by the AP need
not be the same as each other.
The wireless network having any size and complexity may be formed
using the DS and the BSS and the network type may be defined as an
extended service set (ESS) network. The ESS may refer, for example,
to the plurality of BSSs connected to each other through the DS and
may not include the DS. The ESS network has the same logical link
control (LLC) layer as the IBSS network, and therefore the STA
belonging to the ESS may move from one BSS to another BSS within
the same ESS to be transparent to the LLC.
To form physically continuous coverage, the BSSs may partially
overlap with each other. Further, a logical distance between the
BSSs is not limited, and therefore the BSSs may not be physically
connected to each other. Further, to avoid the unnecessary
overlapping, the BSSs may not be physically connected to each
other. Further, for the case in which the ad hoc network is
operated at a position where it has the ESS network, the case in
which the WLAN system networks physically overlapping with each
other are set to have different structures, or the case in which a
plurality of different connections or security policies are
required at the same position, one (or more than that) IBBS or the
ESS network is one (or more than that) ESS network and may be
present in the physically same space.
The STA is logical entity including a physical later interface for
a medium access control (MAC) and a wireless medium and may include
an AP station (AP STA) and a non-AP station (non-AP STA). Among the
STAs, an electronic device manipulated by a user is the non-AP STA,
in which the STA may indicate the non-AP STA. The non-AP STA may be
called other names such as a smart phone, a terminal, a wireless
transmit/receive unit (WTRU), user equipment, a mobile station
(MS), a mobile terminal, and a mobile subscriber unit. Further, the
AP may be entity that provides an access to the distribution system
(DS) through the wireless medium to the station (STA) associated
with the corresponding AP. The AP may also be referred to as a
centralized controller, a base station (BS), a node-B, a base
transceiver system (BTS), a femto BS, a site controller, or the
like.
In the WLAN system, an example of a procedure of connecting the
electronic device to the AP will be described as follows.
The AP may periodically generate and transmit a broadcast type of
beacon frame. The electronic device receiving the beacon frame
senses the presence of the access point. The beacon frame may be
configured to include a header, a frame body, and a frame check
sequence (FCS), and may include information such as a time stamp, a
beacon interval, capability, a service set identifier (SSID), and
supported rates. The service set identifier is an identifier used
to identifier a plurality of different basic service sets in the
WLAN system and may also be called a basic service set identifier
(BSSID).
The electronic device according to an embodiment of the present
disclosure may receive the beacon frames and confirm the presence
of the plurality of APs accessible through the received beacon
frame. Here, the operation may be defined as passive scanning. The
electronic device according to the embodiment of the present
disclosure may select a specific AP from the plurality of APs and
transmit a probe request frame to the selected AP.
The electronic device according to the embodiment of the present
disclosure may store information about the already connected APs as
a profile. The electronic device according to the embodiment of the
present disclosure may store the information about the already
connected APs as the profile, select the AP in a subsequent profile
without receiving the beacon frame, and then transmit a probe
request frame to the selected access point. Here, the operation may
be defined as active scanning.
The probe request frame may be configured to include the header,
the frame body, and the frame check sequence (FCS) and may include
the information such as the service set identifier (SSID), and the
supported rates. The service set identifier is an identifier for
identifying the basic service set and any electronic device that
does not know a unique service set identifier of a specific basic
service set may not access the corresponding basic service set. For
example, the electronic device according to the embodiment of the
present disclosure may carry the service set identifier on the
probe request frame to access the specific basic service set, for
example, the AP.
The AP receiving the probe request frame may transmit a probe
response frame as a response to the probe request frame to the
electronic device. The probe response frame may be configured to
include the header, the frame body, and the frame check sequence
(FCS), and may include information such as the time stamp, the
beacon interval, the capability, the service set identifier (SSID),
and the supported rates. A series of processes as described above
may be defined as a search process.
The electronic device according to the embodiment of the present
disclosure may perform an authentication process with the AP after
going through the search process. For example, the electronic
device receives the probe response frame from the AP and then may
transmit an authentication request frame to the AP to request
authentication. The AP transmits the authentication response frame
to the electronic device, and thus the AP and the electronic device
may establish the authentication relation with each other. The
authentication request frame and/or the authentication response
frame may be configured to include the header, the frame body, and
the frame check sequence (FCS) and may include information such as
an authentication algorithm number, an authentication transaction
sequence number, and a status code.
The electronic device according to the embodiment of the present
disclosure may perform an association process with the AP after
going through the authentication process. For example, after the AP
and the electronic device establish the authentication relation
with each other and then the electronic device may transmit the
association request frame to the AP. The association request frame
may be configured to include the header, the frame body, and the
frame check sequence (FCS) and may include the information such as
the capability, a listen interval, the service set identifier
(SSID), and the supported rates.
The AP according to the embodiment of the present disclosure
transmits the association response frame as a response to the
association request frame to the electronic device, and thus may be
connected to the electronic device. The association request frame
may be configured to include the header, the frame body, and the
frame check sequence (FCS) and may include the information such as
the capability, the status cod, an association ID (AID), and the
supported rates. The association identifier (AID) may refer, for
example, to a specific identifier allocated to each electronic
device for the AP to differentiate the plurality of electronic
devices after the electronic device is associated with the AP.

may include communication circuitry for an access point module (AP
module) 412 for wireless communication between the electronic
device 401 and the WLAN system. The electronic device may use the
AP module 412 to be connected to an AP 402 through the WLAN
system.
The processor 420 (for example: processor 210) controls a general
operation of the electronic device 401 and a signal flow between
internal blocks of the electronic device 401 and may perform a data
processing function of processing data. For example, the processor
420 may be a central processing unit (CPU), a microprocessor unit
(MPU), an application processor, or the like.
When a connection with the specific AP 402 is completed in the WLAN
system, the processor 420 according to the embodiment of the
present disclosure may be set to provide at least one notification
for setting the connected AP 402 to a user. For this purpose, the
processor 420 may acquire setting information about the
corresponding AP 402 during the connection process with the
specific AP 402 and provide the notification for setting the AP 402
to a user when the connection with the specific AP 402 is
completed. Further, the processor 420 may access a server
configured in the AP 402 based on a user input for the notification
and request access authority authentication for the server to the
user. When the access authority is authorized, the processor 420
may provide a detailed screen for setting the AP 402 to the
user.
The processor 420 may acquire AP setting information for setting
the AP 402 from the corresponding AP 402 during the connection
process with the specific AP 402. The AP setting information may
include a default gateway address for accessing the server
configured in the AP 402. The processor 420 may acquire the default
gateway address during the connection process with the
corresponding AP 402, for example, acquire the default gateway
address during the DHCP process of acquiring the IP address from
the AP 402.
The processor 420 may provide notification for setting the AP 402
based on the AP setting information, for example, the default
gateway. The notification may include a text or icon form set to be
linked with an initial web screen for setting the AP 402. The
notification according to the embodiment of the present disclosure
may be provided in a form changing at least one of a form, a font,
a size, and a color of the text. Further, the notification
according to the embodiment of the present disclosure may be
provided in a form changing at least one of a form and a size of
the icon and the number of icons.
The link operation to the initial web screen may be performed by an
access to a port of a server configured in the AP 402 according to
information about the received default gateway. The notification
may be displayed at one side of a name of the currently connected
AP 402 on the screen displaying names of the currently searched APs
402 in a list form. Further, the notification may be provided on
the screen that displays a connection function of a display to the
AP 402, for example, a shortcut icon turning on/off a WLAN

The processor 420 may receive the user input for the notification
through the input device to provide the initial web screen for
setting the currently connected AP 402. The processor 420 may
access the port of the server configured in the AP 420 by referring
to the default gateway address value. The processor 420 may
transmit a setting request message to the server and receive a
permit message from the server to provide interfaces for setting
the AP 402 to a user. The processor 420 may request the authority
authentication, which can access the function of setting the AP
402, to a user prior to providing the screen for setting the AP 402
to the user. For example, the processor 420 may display the initial
web screen and then request the access authority authentication for
the function of setting the AP 402 to the user. The processor 420
may allow a user to provide access authority authentication
information input through the input device to the server and may
provide the detailed setting screen for setting the AP 402 to the
user when getting the access authority authentication from the
server. The processor 420 may communicate with the server
configured in the AP 402 using HTTP protocol to provide the initial
web screen for setting the AP and the detailed setting screen for
setting the AP 402 as described above.
The storage unit 430 (for example: memory 230) may store user data
and data transmitted and received upon communication as well as
application programs required for other option functions, for
example, a sound playing function, an image or moving picture
playing function, a broadcast playing function, or the like, in
addition to an operating system (OS) of the electronic device 401.
The storage unit 430 may store an ID, a password, or the like for
authenticating the access authority for the screen for setting the
AP 402. Therefore, when receiving the request of the access
authority authentication for the AP setting screen from the server
of the AP 402, the processor 420 may refer to the ID and password
stored in the storage unit 430 to automatically perform the
authentication. Further, the storage unit 430 may substitute the
pre-stored ID and password into the changed ID and password under
the control of the processor 420 when the user changes the ID and
password.
The display 440 (for example: display 260) may display the
information input by the user or the information provided to the
user in addition to various menus of the electronic device 401. The
display 440 may communicate with the server of the AP 402 using the
HTTP protocol to provide the initial web screen for setting the AP
and the detailed setting screen for setting the AP 402 based on the
acquired HTML document, under the control of the processor 420. The
display 430 may be formed as a liquid crystal display (LCD), an
organic light emitted diode (OLED), an active matrix organic light
emitted diode (AMOLED), or the like. When the display 430 is formed
in a touch-screen form, the display 430 may be operated as the
input device 450.
The input device 450 (for example; input device 250) may include
various input circuitry that receives numerals or various character
information and may include an input key and a functional key for
setting various functions and controlling the function of the
electronic device 401. The input device 450 according to the
embodiment of the present disclosure may receive the notification
for setting the currently connected AP 402, for example, the user

embodiments of the present disclosure, a detailed setting screen
for setting the specific AP.
Referring to FIG. 5, the method of connecting and setting an
electronic device according to various embodiments of the present
disclosure to and in a specific AP may include an operation (512)
of trying to connect a processor to an AP, an operation (514) of
allocating an IP to the processor from a server configured in the
AP during a DHCP process, an operation (516) of acquiring, by the
processor, a default gateway address from the server during the
DHCP process, an operation (518) of providing notification
associated with the setting of the AP based on the default gateway
address acquired by the processor, an operation (520) of
determining a user input for the notification an operation (522) of
displaying an initial screen for setting the AP based on the user
input for the notification, an operation 524 of receiving, by the
processor, a request of access authority authentication for the
screen for setting the AP from the server of the AP 402 to request
the authority authentication to a user, and an operation (526) of
providing a setting function for the AP to the authorized user.
In the operations 512, 514, and 516, the processor 420 may start
the connection to the specific AP through the communication circuit
based on the user input. For example, the processor 420 may be
allocated the IP from the AP by performing the DHCP process.
Further, the processor 420 may acquire the AP setting information,
for example, the default gateway address of the AP. In detail,
referring to FIG. 6, the processor 420 of the electronic device 601
according to the embodiment of the present disclosure may transmit
a DHCP discover message requesting an IP address to an AP 602. The
processor 420 of the electronic device 601 may transmit the DHCP
discover message in a broadcast type since it does not know the IP
address of the electronic device 601 and the IP of the AP 602 that
is the DHCP server. The AP 602 receiving the DHCP discover message
may transmit a DHCP offer message to the electronic device 601 as a
response thereto. The DHCP offer message may include information
such an IP address allocated from the AP 602, a subnet mask, a
period, and a DHCP address. The AP 602 may transmit the DHCP offer
message in the broadcast type. The processor 420 may select a
specific IP address among the IP addresses included in the DHCP
offer message and transmit a DHCP request message to request the
selected IP address to the AP 602. The AP 602 may transmit a DHCP
acknowledge (Ack) message to complete the allocation of the IP
address to the electronic device 601. The DHCP discover message may
be a message transmitted to first allocate an IP address to the
electronic device 601. Therefore, after the electronic device 601
is allocated the IP address and then the IP address expires, the
transmission of the DHCP discover message may be omitted. When the
processor 420 again requests the IP address to the AP 602, the
processor 420 transmits the DHCP request message to the AP 602 and
thus may be allocated the IP address.
In particular, the processor 420 according to the embodiment of the
present disclosure may receive the AP setting information during
the DHCP process. For example, the processor 420 may receive the AP
setting information (for example: default gateway address) in the
operation of receiving the DHCP offer message.
In the operation 518, if the processor 420 is allocated the IP when
the connection to the AP is completed, the processor 420 may
provide the notification for setting the AP 402 based on the AP
setting information, for example, the default gateway. The
notification may include a text or icon form set to be linked an
initial web screen for setting the AP 402. The notification
according to the embodiment of the present disclosure may be
provided in a form changing at least one of a form, a font, a size,
and a color of the text. Further, the notification according to the
embodiment of the present disclosure may be provided in a form
changing at least one of a form and a size of the icon and the
number of icons.
As illustrated in FIG. 8A, the notification 802 may be displayed at
one side of a name of the currently connected AP 402 on the screen
displaying names of the currently searched APs 402 in a list form.
As illustrated in FIG. 8B, the processor 420 may provide the
detailed information screen 804 associated with the current AP when
selecting a region, in which the name of the currently connected AP
is displayed, from the list. The processor 420 may provide the
notification 802 in an icon form and a notification 806 in a text
form on the detailed information screen.
As illustrated in FIG. 9, the processor 420 according to the
embodiment of the present disclosure may provide the notification
on the screen that displays a connection function of a display to
the AP 402, for example, a shortcut icon turning on/off a WLAN
connection function. For example, the processor 420 may display a
shortcut icon window 902 one side of the screen on which the
display is displayed, for example, an upper side of the screen. The
shortcut icon window 902 may be provided with a plurality of
shortcut icons for rapidly setting various functions provided from
the electronic device 401, for example, may be provided with a
shortcut icon 904 turning on/off the WLAN connection function. As
such, when the shortcut icon window 902 is displayed, the processor
420 may provide a notification 906 to a position adjacent to the
shortcut icon 904 turning on/off the WLAN connection function. The
notification 906 may be the text form or the icon form.
In the operation 520, the processor 420 may determine whether the
user input for the notification is generated. The processor 420 may
recognize a user selection for the notification by sensing a simple
touch input depending on the user input for the notification.
Further, the processor 420 may recognize the user selection for the
notification depending on the user input for the notification that
is sustained over a specific time. For example, the processor 420
may determine whether the user input for the notification is
generated through the input device and compare the sustained time
of the user input with a reference time when the user input is
generated. When the sustained time of the user input exceeds the
reference time, the processor 420 may recognize that the user
selects the notification to perform a control to display the
initial web screen on the display.
In the operation 522, the processor 420 may display the initial web
screen for setting the AP based on the user input for the
notification. For example, as illustrated in FIG. 10, the processor
420 may input the default gateway address to a next address window
1002 executing a browser when the user input for the notification
is generated to display an initial web screen 1004 for providing
the AP setting function. The processor 420 may display the initial
web screen 1004 based on HTML document information received through
the port of the server configured in the AP and corresponding to
the default gateway address. For example, if the processor 420 is
allocated the IP when the connection with the specific AP is
completed, the processor 420 may transmit the setting request
message for accessing the setting function of the AP to the server
of the AP. The processor 420 may receive a permit message from the
server of the AP receiving the setting request message, receive the
HTML document information for displaying the initial web screen,
and display the initial web screen based on the HTML document
information.
In the operation 524, the processor 420 may request the access
authority authentication for the function of setting the AP to a
user. For example, as illustrated in FIG. 11, the processor 420 may
provide an authentication request screen 1102 to a user when the
user tries the AP setting in the initial web screen state. The
access authority for the function of setting the AP may be provided
to the user, having a unique ID and password set during the process
of producing the AP at an early stage. The user may input the
unique ID and password set for the AP through the input device to
perform the authority authentication. When the storage unit 430
pre-stores the unique ID and password, the processor 420 may
automatically perform the access authority authentication for the
function of setting the AP. Therefore, when the ID and the password
are pre-stored, the processor 420 may not provide the screen
requesting the access authority authentication for the function of
setting the AP.
In the operation 526, the processor 420 may provide the AP setting
screen to the authorized user. For example, the processor 420 may
transmit the received ID and password to the server of the AP
through the input device. As illustrated in FIG. 12, when receiving
the access authority authentication message from the server, the
processor 420 may provide the detailed setting screen for setting
the AP to the user. The processor 420 may receive the
authentication message and receive the HTML document information
for displaying the detailed setting screen.
Referring to FIG. 7, the method of connecting and setting an
electronic device according to various embodiments of the present
disclosure to and in a specific AP may include an operation (712)
of confirming availability of an IP address allocated from a
server, an operation (714) of determining whether a currently
connected AP is a mobile hot spot, an operation (716) of
determining whether the currently connected AP is an enterprise AP,
an operation (718) of determining whether the currently connected
AP is an operator AP, an operation (720) of determining whether the
currently connected AP is a captive portal AP, and an operation 722
of displaying only basic information of the currently connected AP
as a default. Further, the method of connecting and setting an
electronic device according to various embodiments of the present
disclosure to and in a specific AP may further include an operation
(724) of providing a notification or a user interface connectable
to a web authentication server when the currently connected AP is
the captive portal AP, an operation (726) of providing an
authentication page for authenticating a use of a network through
the captive portal AP, and an operation (728) of performing
authentication based on a user input for the notification or the
user interface.
In the operation 712, the processor 420 may confirm the
availability of the IP address allocated from the AP. In detail,
the IP address allocated from the AP may not be effective when an
error of the DHCP or an equipment error of the AP occurs.
Therefore, the processor 420 may confirm the allocated IP address
to previously determine when the Internet connection and the
transmission and reception of packet through the AP may not be
made. For example, the processor 420 may try a transmission control
protocol (TCP) connection to the allocated IT address. The TCP
connection may include a TCP 3 way handshaking process. When the
TCP connection succeeds, the processor 420 may determine whether
the corresponding IP address is effective and when the TCP
connection fails, the processor 420 may determine whether the
corresponding IP address is not effective.
In the operations 714, 716, and 718, the processor 420 may
determine whether the currently connected AP belongs to a first
group that may change the setting or a second group that may not
change the setting. The first processor 420 may display the
notification on the display when the connected AP belongs to the
first group and display only the basic information about the AP
other than the notification when the connected AP belongs to the
second group. The APs that belong to the first group is an opening
AP that has been widely used and may be a personal WLAN router. The
APs belonging to the second group may not be set, and may include,
for example, the mobile hot spot, the enterprise AP, and the
operator AP. Therefore, the processor 420 may display only the
basic information on the corresponding AP when the currently
connected AP is any one of the mobile hot spot, the enterprise AP,
and the operator AP. For example, in the operation 714, the
processor 420 may confirm whether the currently connected AP is the
mobile hot spot by confirming whether the IP allocated from the
DHCP server is in a range used by a specific vendor. Further, in
the operation 716, the processor 420 may confirm whether the
currently connected AP is the enterprise AP by confirming WPA
Key_mgmt information in a beacon frame where the AP is periodically
transmitted.
In the operation 718, the processor 420 may confirm whether the
currently selected AP is the operator AP by confirming operator
profile information pre-stored in a memory upon the release of
products. Further, in the operation 720, the processor 420 may
confirm whether the currently selected AP is the captive portal AP
by confirming a redirection As such, the method may further include
the operation (724) of providing a notification or a user interface
connectable to a web authentication server when the currently
connected AP is the captive portal AP, the operation (726) of
providing an authentication page for authenticating a use of a
network through the captive portal AP, and the operation (728) of
performing authentication based on a user input for the
notification or the user interface.
As the 802.11i WPA standard as a security technology of the 802.11
network is diffused, the captive portal AP has been used. This is a
technology of implementing a user authentication and billing system
of a wireless network as the communication standard. The captive
portal AP is not for wireless LAN security authentication for
enterprise but is for provision of low level security to
unspecified users. Therefore, the captive portal AP may mainly be
used for places such as a hotel and an airport in and out which
people come and go and may be a service providing a wireless LAN
service to people paying a fee. If the electronic device according
to the embodiment of the present disclosure is connected to the AP
to which the captive portal is applied, the connection of the WLAN
level based on the 802.11 open system authentication may be
completed. After the electronic device is connected to the captive
portal AP, when a user first tries to open any web page, the
electronic device intercepts the corresponding HTTP GET message on
a network and may redirect the intercepted message to an
authentication server page of the wireless network. The electronic
device may provide an Internet service to a user through the
captive portal AP only after transmitting the authentication
information required by the authentication server.
When the electronic device according to the embodiment of the
present disclosure is connected to the captive portal AP, the
electronic device permits the Internet connection service only for
a specific time of the user authentication, for example, 12 hours,
24 hours, and 1 week and may provide a scheme of inducing
repurchasing of re-authentication or authentication information
after the specific time ends. Accordingly, the electronic device
according to the embodiment of the present disclosure may provide
the notification or the user interface that may directly access the
purchase authentication page to the user when the currently
connected AP is the captive portal AP. The notification or the user
interface for the authentication page of the captive portal AP may
include the text or icon form. The notification or the user
interface may be provided in a form changing at least one of a
form, a font, a size, and a color of the text. Further, the
notification or the user interface according to the embodiment of
the present disclosure may be provided in a form changing at least
one of a form and a size of the icon and the number of icons.
In the operation 722, when the IP address allocated from the
currently connected AP is not effective or the currently connected
AP is the second group, for example, any one of the mobile hot
spot, the enterprise AP, and the operation AP, the processor 420
may display only the basic setting information of the corresponding
AP and may not display the notification for changing the setting of
the AP.
The processor 420 according to the embodiment of the present
disclosure may classify even the captive portal AP into the second
group, in addition to the mobile hot spot, the enterprise AP, and
the operator AP. Therefore, even when the currently connected AP is
the captive portal AP, the processor 420 may provide only the basic
setting information that the corresponding AP is the captive portal
AP.
As described above, it is possible to improve the user convenience
by easily accessing the screen for security setting of the AP and
prevent the security issue by easily changing the security setting
of the AP.
A programming module according to embodiments of the present
disclosure may include one or more of the aforementioned components
or may further include other additional components, or some of the
aforementioned components may be omitted. Operations executed by a
module, a programming module, or other component elements according
to various embodiments of the present disclosure may be executed
sequentially, in parallel, repeatedly, or in a heuristic manner.
Further, some operations may be executed according to another order
or may be omitted, or other operations may be added.
While the disclosure has been illustrated and described with
reference to certain embodiments thereof, it will be understood by
those skilled in the art that various changes in form and detail
may be made therein without departing from the spirit and scope of
the disclosure as defined by the appended claims.
